100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

What do we need to believe in in order to reach our goals? Filip Smeets CEO of Hydrogenics Europe set the tone of the thrid day by pointing to the need to focus on a realiststic deployment plan in order to develop a market for energy storage and grid balancing in parallel to renewable power roll out the development of a truly sustainable. Simon Bourne, Chief Technology Officer  of ITM Power indicated that as of 20% renewable wind capacity in the nenergy mix: In hte Uk over a 1000GW was not used in 2015 . Over 1 £bln was spend on grid balancing in 204-2015. As wind turbine is turning to high the frequency goes down . Their are two responses: the quick one to restore frequencies. Eletrolysers are very effective and responsive to power intermittence. The gas network has five times the capacity of the eletricity network. A 2015 UKHSA  study on injecting hydrogen in the gas network concluded that there were no negative impact of 20% of H2 in the gas grid, nor on the pipes and that such gas mixture did not pose more safety problems

 

Gregor Waldstein managing director ETOGAS of Switzerland presented is activities to produce syngas starting form the CO2 capture of biogas production combined with renwable hydorgen: in this way the biogas production can be boosted. HE is referring to the need to abadon taxation of the grid enabling devices ad to adapt the national plans in 2017 for the EU Renewable Energy Directiive an Fuel Quality Directive in orderto recognize renewable hydorgen as well.

Wes Anderson, CTO of Proton-on-Site installed its first Power to Gas at SoCalGas Irvien California and a unit at university that has Transmission Level Service and were caught up with up to $ 1 mln demnad charges. They had to optimize their wind power and looked at battey (negative as ROI was 20 years, electrolyser/fuel cell with ROI 15 yrs as Eletrolyzer with gas turbine combination was 4,5 years.

In the Hydrogen Infrastructure session CEA Camilla Cely indicated that more renewable energy in France shoudl not reduce nuclear power output if hydrpgen production is introduced as a means to secure base load operations in nuclear plants. UCL Shipping emissions acoount for 3% according the International Maritime Organisation.

Modelling of Japan’s BEV and FCEV fleet in Japan and New Zealand, as a joint effrot of Unitec Auckland New Zealand and the university of Kanagawa Yokohama, concluded that 90% reduction in emissions is possible with BEV and FCEV. Penetration rates comparisons of new technologies were compared of the Prius over 20 years (over 30%),  of the Nissan Leaf (over 30%) and of the first Ford (over 30%, except for the war years 2014 – 2018): in 2060 this would trnaslate into 20% of eletricity needed for zero emissions transport with FCEV.

The Hydrogen infrastructure session in the afternoon included modelling of the Spanish, USA FCEV and HRS deployment that differed significantly with regards to  projections for 2030: estimates for Spain were 20 fold the figures of the H2MobilitàItaly consortium that will present its roadmap to the Italian overnment on July 9.

At sunset the FCH crowd floated above the Ebro river winding down of three days emersion into more than 30o presentations. They should be screened on the now empty billboards on the Expo site!
